电机及其控制英文作文英文：Electric motors are a crucial component in many industries, from manufacturing to transportation. They convert electrical energy into mechanical energy, allowing for the movement of machinery, vehicles, and other equipment. The control of electric motors is also important, as it allows for precise adjustments in speed and direction.There are various types of electric motors, includingAC motors, DC motors, and stepper motors. Each type has its own unique characteristics and applications. For example, AC motors are commonly used in household appliances, while DC motors are often used in electric vehicles. Stepper motors are used in applications that require precise control, such as 3D printers.The control of electric motors can be achieved through various methods, such as using a motor controller or avariable frequency drive. These devices allow for the adjustment of the motor's speed and direction, as well as providing protection against overloading and overheating.In my experience, I have worked with electric motors in the automotive industry. We used DC motors to powerelectric vehicles, and the control of these motors was crucial for the performance of the vehicle. We used a motor controller to adjust the speed and direction of the motor, and to ensure that it did not overheat or overload.Overall, electric motors and their control play a vital role in many industries, and understanding their operation and application is important for anyone working in these fields.中文：电动机是许多行业的关键组件，从制造业到交通运输。

电机起动系统：电机尤其是大电机的起动对电动机构的运行效率起着非常重要的作用。
可以用几种不同的系统起动电机。
使用的电机起动装置位于电源和电机之间。
在起动过程中，电机从电源获得一个比正常运行时大得多的电流。
通常用电机起动装置将起动电流减小到一个电力系统可以控制的水平。
1、全压起动电机起动的方法之一叫全压启动。
这种方法投资便宜而且安装简单。
由于额定电压从起动初始就施加到电机上，所以会产生最大起动转矩和最小加速时间。
然而，电力系统必须能控制由电机汲取的起动电流。
2、主电阻起动电机起动的另一种方法叫主电阻起动。
这种方法将大电阻串联在线路中，以减小电机的起动电流。
通常，连接在线路中的电阻逐级减小，直到额定电压全部加在电机上。
这样，起动转矩随着流过的电流幅值而减小，而起动电流又将随着线路中串联的电阻值而减小。
3、主电抗起动另一种电机起动方法与主电阻起动相似，叫主电抗起动。
这种方法是用电抗器（线圈）替代电阻器，因为在交流电时它们消耗较少的能量。
这种方法通常更适用于额定电压超过600伏的大电机。
4、自耦变压器起动自耦变压器起动是用于电机起动的另一种方法。
这种方法使用一个或多个自耦变压器来控制加在电机上的电压。
接入的自耦变压器通常用于提供一个起动电流控制范围。
当电机加速到它的额定转速附近时，从线路中去掉自耦变压器绕组。
这种方法的主要缺点是自耦变压器的花费大。
5、星形－三角形起动使用星形－三角形起动可能是起动三相电机更为经济的方法。
对星形接法，相电压等于线电压的1.73倍，所以使用星形结构比使用三角形结构起动电流更小。
这种方法在起动时用一个开关使电机定子绕组以星形结构排布，在运转时又以三角形结构排布。
用这种方法减小了起动电流。
6、直流起动系统由于直流电机在不旋转时没有反电动势，它的起动电流非常大。
因此必须使用某种控制系统，例如用一个串联电阻来减小初始的起动电流。
可以手动或自动减小电阻，直到全电压加到电机上。
直流电机常用的4种类型控制系统是：电流限制，定时，反电动势，可变电压。

In the first part of this discussion, we are concerned with the . Structurally, this transistor is described as bipolar because it has two different current-carrier polarities.首先探讨双极型晶体管。
从结构上看，这种晶体管被称为双极是因为它具有两种不同的电流载流子电极。
Holes are positive current carriers, whereas electrons are negative current carriers.空穴是正的载流子，电子是负的电流载流子。
Two distinct kinds of semiconductor crystals are connected together by a common element. 两种截然不同的半导体晶体通过公共元件连接在一起。
The structure of this device is similar to that of two diodes connected back to back, with one crystal being common to both junctions. The center material is usually made thinner than the two outside pieces. 该器件的结构类似于背靠背连接的两个二极管的结构，一个晶体同时属于两个结。
电动机控制中英文对照外文翻译文献
电动机控制中英文对照外文翻译文献(文档含英文原文和中文翻译)原文：Control of Electric winchFor motor control, we know the best way is to use the style buttons to move the many simple manual console. And this console, in some applications may still be a good choice, as some complex control headache can also be used. This article describes in your design, build or purchase winch controller, you have the motor's basic electrical equipment and you will need to address the user interface command addressed.First, the manual should be a manual control console type, so if you remove your finger buttons, hoist will stop. In addition, each control station equipped with an emergency need to brake, hoist the emergency brake to cut off all power, not just the control circuit. Think about it, if the hoist at the stop, it did not stop, you do need a way to cut off the fault line protection power. Set the table in the control of a key operated switch, is also a very good idea, especially in the line leading to theworkstation can not control, you can use the switch.(in the design of the console, even the simplest manual console, but also consider setting by specialized personnel to operate the safe operation of the keys.) Constant speed motor controlFor a fixed speed winch actual control device is a three-phase starter. Turn the motor is reversed, by a simple switch controlled phase transformation sequence from ABC to CBA. These actions are completed by two three-pole contactor-style, and they are interlocked, so that they can not be simultaneously closed. NEC, required in addition to overload and short circuit protection devices. To protect the motor against overload due to mechanical effects caused by overheating in the heat to be installed inside the starter overload delay device. When the heat overload delay device overheating, it has a long double off the metal motor power. In addition In addition, you can also select a thermistor can be installed in the motor winding way, it can be used to monitor motor temperature changes. For the short-circuit protection, we generally used by motor fuses to achieve.A linear current independent contactors, the contactors are configured should be more than the current main circuit contactor, so as to achieve the purpose of redundancy. This sets the current contactor is controlled by the security circuit, such as: emergency brake and the more-way limits.We can use the limit switches to achieve the above operation. When you reach the end of the normal travel limit position, the hoist will stop, and you can only move the winch in the opposite direction (ie, the direction away from the limit position.) There is also need for a more limited way just in case, due to electrical or mechanical problems, leaving the operation of hoist limit bit more than normal. If you run into more limiter, linear contactor will open, therefore, can not be driven winch will exceed this limit position. If this happens, you need to ask a professional technician to check the lead to meet the more specific reasons limiter. Then, you can use thestarter toggle switch inside the elastic recovery process to deal with more problems, rather than tripping device or a hand-off the current contacts.A necessary condition for speedOf course, the simple fixed speed starter is replaced by variable speed drives. This makes things start to get interesting again! At a minimum, you need to add a speed control dial operation platform. Joystick is a better user interface, because it makes you move parts of a more intuitive control.Unfortunately, you can not just from your local console to send commands to control the old variable speed drives, in addition, you can not want it in the initial stages, will be able to enhance the safe and reliable and decentralized facilities. Most of the variable speed drive can not achieve these requirements, because they are not designed to do upgrading work. Drivers need to be set to release the brake before the motor can generate torque, and when parking, that is, before the revocation of torque, the brake will be the first action.For many years, DC motors and drives provide a number of common solutions, such as when they are in a variety of speeds with good torque characteristics. For most of the hoist of the large demand for DC motor is very expensive, and that the same type of AC motor than the much more expensive. Although the early AC drives are not very useful, as they have a very limited scope of application of the speed, but produced only a small low-speed torque. Now, with the DC drives the development of low cost and a large number of available AC motors has led to a communication-driven revolution.Variable speed AC drives in two series. Frequency converter has been widely known and, indeed, easy to use. These drives convert AC into DC, and then, and then convert it back to exchange, the exchange after the conversion is a different frequency. If the drive produced the exchange of 30Hz, 60Hz a normal motor will run at half speed. Theoretically, this is very good, but in practice, this will have a lot of problems. First of all, a typical linear motor 60Hz frequencies below 2Hz 3Hz area or there will be errors, and start cog (that urgent push, yank), or parking. This will limit your speed range lower than 20:1, almost not adapted to the operational phase of the fine adjustment. Second, many low-cost converter is not able to provide the rated torque at low speeds. Use of these drives, will result in the rapid move to upgrade the components or complete failure, precisely, when you try to upgrade a stable scientific instruments, you do not want to see this situation. Some new inverter is a closed-loop system (to get feedback from the motor to provide a more accurate speed control), and the motor will work quite well.Another series of AC drives is the flow vector type drive. These components require installation of the spindle motor encoder, encoder makes use of these drivescan accurately monitor the rotation of the motor armature. Processor accurately measured magnetic flux vector values that are required to make the armature at a given speed rotation. These drives allow infinite speed, so you actually can produce at zero speed to rated torque. These drives provide precise speed and position control, so these drives in high performance applications to be welcomed.(Based on PLC controllers provide system status and control options. This screen shows the operator full access to the nine-story elevator enhance the control panel.) PLC-based systemsIs the full name of a PLC programmable logic controller. First of all, PLC controller developed to replace the fifties and sixties-based industrial control system relay, they work in harsh industrial indoor environments. These are modular systems that have a large variety of I / O modules. The modular system can easily achieve the semi-custom hardware configuration assembled, and the resulting configuration is also very reasonable price. These modules include: position control module, the counter, A / D and D / A converter, and a variety of physical state or physical contact with closed output module. Large number of different types of I / O components and PLC module property makes it an effective way to assemble custom and semi custom control system.The biggest shortcoming of PLC systems is the lack of the real number of display to tell you what is being done and the PLC on the PLC program to help you.T he first is professional entertainment for the large-scale PLC system is one of the original in Las Vegas, MGM (now Bailey Company) of the riding and carriage system. Many manufacturers offer a standard PLC-based semi-automated acoustic systems and a host of signs, set the location of the command line interpreter, and the upgrading of the control system is also available. Using standard modules to set user-defined system configuration capability is based on the PLC controller of the greatest advantage.High-end controllerFor complex transmission, the controller became complex, more than speed, time and location control. They include complex instructions to write and record the movement contour, and the processing can immediately run the ability to multi-point instructions.Many large opera house is toward the direction of point lift system, where each one is equipped with a rope to enhance independent winches, rope equivalent to those of each dimmer circuit. When more than one hoist is used to enhance the individual part, the hoist must be fully synchronous, or the load to shift, so will lead to a separate winch becomes the risk of overload. Control system must be able to be selected to keep pace winch, or a hoist winch is not able to maintain synchronization with the other, can provide the same high-speed parking capacity. For a typical speed of 240 ft / min and a winch to maintain the rate of error of between 1 / 8 points of equipment, you only have less than three microseconds of time to identify problems and try to correct the error The hoist speed, make sure you fail, you start all the winch stop the group. This will require a large amount of computation, fast I / O interface, and easy to use to write software.For large rope control system has two very different solutions. The first is to use a separate console, the problem in general terms, this console should be installed in the appropriate location of the operator perspective. However, this not only from one angle to another angle, but still can not get an instruction to another instruction from the control. These difficulties have been partially resolved.

电动机控制中英文对照外文翻译文献
电动机控制中英文对照外文翻译文献(文档含英文原文和中文翻译)原文：Control of Electric winchFor motor control, we know the best way is to use the style buttons to move the many simple manual console. And this console, in some applications may still be a good choice, as some complex control headache can also be used. This article describes in your design, build or purchase winch controller, you have the motor's basic electrical equipment and you will need to address the user interface command addressed.First, the manual should be a manual control console type, so if you remove your finger buttons, hoist will stop. In addition, each control station equipped with an emergency need to brake, hoist the emergency brake to cut off all power, not just the control circuit. Think about it, if the hoist at the stop, it did not stop, you do need a way to cut off the fault line protection power. Set the table in the control of a key operated switch, is also a very good idea, especially in the line leading to theworkstation can not control, you can use the switch.(in the design of the console, even the simplest manual console, but also consider setting by specialized personnel to operate the safe operation of the keys.) Constant speed motor controlFor a fixed speed winch actual control device is a three-phase starter. Turn the motor is reversed, by a simple switch controlled phase transformation sequence from ABC to CBA. These actions are completed by two three-pole contactor-style, and they are interlocked, so that they can not be simultaneously closed. NEC, required in addition to overload and short circuit protection devices. To protect the motor against overload due to mechanical effects caused by overheating in the heat to be installed inside the starter overload delay device. When the heat overload delay device overheating, it has a long double off the metal motor power. In addition In addition, you can also select a thermistor can be installed in the motor winding way, it can be used to monitor motor temperature changes. For the short-circuit protection, we generally used by motor fuses to achieve.A linear current independent contactors, the contactors are configured should be more than the current main circuit contactor, so as to achieve the purpose of redundancy. This sets the current contactor is controlled by the security circuit, such as: emergency brake and the more-way limits.We can use the limit switches to achieve the above operation. When you reach the end of the normal travel limit position, the hoist will stop, and you can only move the winch in the opposite direction (ie, the direction away from the limit position.) There is also need for a more limited way just in case, due to electrical or mechanical problems, leaving the operation of hoist limit bit more than normal. If you run into more limiter, linear contactor will open, therefore, can not be driven winch will exceed this limit position. If this happens, you need to ask a professional technician to check the lead to meet the more specific reasons limiter. Then, you can use thestarter toggle switch inside the elastic recovery process to deal with more problems, rather than tripping device or a hand-off the current contacts.A necessary condition for speedOf course, the simple fixed speed starter is replaced by variable speed drives. This makes things start to get interesting again! At a minimum, you need to add a speed control dial operation platform. Joystick is a better user interface, because it makes you move parts of a more intuitive control.Unfortunately, you can not just from your local console to send commands to control the old variable speed drives, in addition, you can not want it in the initial stages, will be able to enhance the safe and reliable and decentralized facilities. Most of the variable speed drive can not achieve these requirements, because they are not designed to do upgrading work. Drivers need to be set to release the brake before the motor can generate torque, and when parking, that is, before the revocation of torque, the brake will be the first action.For many years, DC motors and drives provide a number of common solutions, such as when they are in a variety of speeds with good torque characteristics. For most of the hoist of the large demand for DC motor is very expensive, and that the same type of AC motor than the much more expensive. Although the early AC drives are not very useful, as they have a very limited scope of application of the speed, but produced only a small low-speed torque. Now, with the DC drives the development of low cost and a large number of available AC motors has led to a communication-driven revolution.Variable speed AC drives in two series. Frequency converter has been widely known and, indeed, easy to use. These drives convert AC into DC, and then, and then convert it back to exchange, the exchange after the conversion is a different frequency. If the drive produced the exchange of 30Hz, 60Hz a normal motor will run at half speed. Theoretically, this is very good, but in practice, this will have a lot of problems. First of all, a typical linear motor 60Hz frequencies below 2Hz 3Hz area or there will be errors, and start cog (that urgent push, yank), or parking. This will limit your speed range lower than 20:1, almost not adapted to the operational phase of the fine adjustment. Second, many low-cost converter is not able to provide the rated torque at low speeds. Use of these drives, will result in the rapid move to upgrade the components or complete failure, precisely, when you try to upgrade a stable scientific instruments, you do not want to see this situation. Some new inverter is a closed-loop system (to get feedback from the motor to provide a more accurate speed control), and the motor will work quite well.Another series of AC drives is the flow vector type drive. These components require installation of the spindle motor encoder, encoder makes use of these drivescan accurately monitor the rotation of the motor armature. Processor accurately measured magnetic flux vector values that are required to make the armature at a given speed rotation. These drives allow infinite speed, so you actually can produce at zero speed to rated torque. These drives provide precise speed and position control, so these drives in high performance applications to be welcomed.(Based on PLC controllers provide system status and control options. This screen shows the operator full access to the nine-story elevator enhance the control panel.) PLC-based systemsIs the full name of a PLC programmable logic controller. First of all, PLC controller developed to replace the fifties and sixties-based industrial control system relay, they work in harsh industrial indoor environments. These are modular systems that have a large variety of I / O modules. The modular system can easily achieve the semi-custom hardware configuration assembled, and the resulting configuration is also very reasonable price. These modules include: position control module, the counter, A / D and D / A converter, and a variety of physical state or physical contact with closed output module. Large number of different types of I / O components and PLC module property makes it an effective way to assemble custom and semi custom control system.The biggest shortcoming of PLC systems is the lack of the real number of display to tell you what is being done and the PLC on the PLC program to help you.T he first is professional entertainment for the large-scale PLC system is one of the original in Las Vegas, MGM (now Bailey Company) of the riding and carriage system. Many manufacturers offer a standard PLC-based semi-automated acoustic systems and a host of signs, set the location of the command line interpreter, and the upgrading of the control system is also available. Using standard modules to set user-defined system configuration capability is based on the PLC controller of the greatest advantage.High-end controllerFor complex transmission, the controller became complex, more than speed, time and location control. They include complex instructions to write and record the movement contour, and the processing can immediately run the ability to multi-point instructions.Many large opera house is toward the direction of point lift system, where each one is equipped with a rope to enhance independent winches, rope equivalent to those of each dimmer circuit. When more than one hoist is used to enhance the individual part, the hoist must be fully synchronous, or the load to shift, so will lead to a separate winch becomes the risk of overload. Control system must be able to be selected to keep pace winch, or a hoist winch is not able to maintain synchronization with the other, can provide the same high-speed parking capacity. For a typical speed of 240 ft / min and a winch to maintain the rate of error of between 1 / 8 points of equipment, you only have less than three microseconds of time to identify problems and try to correct the error The hoist speed, make sure you fail, you start all the winch stop the group. This will require a large amount of computation, fast I / O interface, and easy to use to write software.For large rope control system has two very different solutions. The first is to use a separate console, the problem in general terms, this console should be installed in the appropriate location of the operator perspective. However, this not only from one angle to another angle, but still can not get an instruction to another instruction from the control. These difficulties have been partially resolved. Installed in different locations through the use of video cameras, and these cameras connected to the three-dimensional display graphics, these graphics enables the operator to observe from the perspective of any of the three coordinates in the expected direction of rope movement. These operators can make from a console for him at the actual angle, or closed circuit camera practical perspective, to observe the movement of the rope on the screen. For the complex interrelated moving parts, makes the implementation of the above observation Failure to control and find out easier.Another solution to the problem is a distributed system that uses multiple light console.

电机控制计划英文版Motor Control Scheme.In the field of industrial automation, the control of electric motors is of paramount importance. Proper motor control enables precise positioning, speed regulation, and torque control, which are essential for a wide range of industrial applications, from robotics to manufacturing machinery. Various motor control schemes have been developed over the years, each with its own advantages and disadvantages.Open-Loop Control.Open-loop control is the simplest motor control scheme, where the motor is driven by a fixed voltage or current without any feedback mechanism. This scheme is easy to implement and cost-effective, but it offers limited accuracy and robustness. Variations in motor parameters, load conditions, and environmental factors can lead tosignificant errors in motor performance.Closed-Loop Control.Closed-loop control addresses the limitations of open-loop control by incorporating a feedback mechanism. This feedback loop measures the actual motor output, such as speed or position, and compares it to the desired reference value. The difference between the actual and desired values is then used to adjust the motor input, ensuring that the motor output closely follows the reference.There are various types of closed-loop motor control schemes, each employing different feedback and control algorithms.Proportional-Integral-Derivative (PID) Control: PID control is a widely used closed-loop scheme that adjusts the motor input based on the proportional, integral, and derivative of the error signal. It is simple to implement and offers good performance for a wide range of applications.State-Space Control: State-space control utilizes a mathematical model of the motor to design a closed-loop controller. This scheme provides excellent performance and stability, but it requires a more complex implementation and tuning process.Model Predictive Control (MPC): MPC is an advanced closed-loop control scheme that predicts the future behavior of the motor based on a mathematical model. This prediction allows for optimal control actions that minimize errors and improve system performance.Brushed DC Motor Control.Brushed DC motors are widely used in various applications due to their low cost, simplicity, and ease of control. The basic principle of brushed DC motor control involves varying the voltage or current supplied to the motor's terminals. By adjusting the voltage or current levels, the motor's speed and torque can be controlled.Simple Voltage Control: Simple voltage control involves varying the voltage supplied to the motor's terminals. This method is easy to implement but offers limited speed regulation.Pulse-Width Modulation (PWM) Control: PWM control utilizes a switching device, such as a transistor, to rapidly switch the voltage supplied to the motor. By varying the duty cycle of the PWM signal, the average voltage applied to the motor can be controlled, resulting in precise speed regulation.Brushless DC Motor Control.Brushless DC (BLDC) motors offer several advantages over brushed DC motors, including higher efficiency, longer lifespan, and reduced maintenance. BLDC motors require more complex control algorithms due to their inherently nonlinear characteristics.Six-Step Commutation: Six-step commutation is a basic BLDC motor control scheme that involves energizing themotor's stator windings in a specific sequence to produce a rotating magnetic field. This scheme is simple to implement but can result in torque ripple.Field-Oriented Control (FOC): FOC utilizes mathematical transformations to decouple the motor's torque and flux components. This allows for independent control of the motor's speed and torque, resulting in improved performance and efficiency.Stepper Motor Control.Stepper motors are widely used in applicationsrequiring precise positioning, such as 3D printers and CNC machines. Stepper motors are controlled by sending a sequence of pulses to the motor's driver, which energizes the motor's windings in a specific order.Open-Loop Stepper Control: Open-loop stepper control involves sending a fixed number of pulses to the motor's driver. This method is simple to implement but can lead to errors in positioning due to variations in motor parametersand load conditions.Closed-Loop Stepper Control: Closed-loop stepper control incorporates a feedback mechanism, such as an encoder, to measure the motor's actual position. This feedback loop ensures accurate positioning by adjusting the motor's input based on the difference between the actual and desired positions.Selection of Motor Control Scheme.The selection of an appropriate motor control scheme depends on the specific application requirements. Factors to consider include:Performance Requirements: The desired accuracy, precision, and speed regulation capabilities of the motor.Cost and Complexity: The available budget and resources for implementing and maintaining the control system.Environmental Conditions: The temperature, humidity, and other environmental factors that the motor will be subjected to.Motor Type: The characteristics and limitations of the specific motor being used.By carefully considering these factors, engineers can select the optimal motor control scheme to meet thespecific demands of their industrial application.。

第七章____电机控制系统(双语)
7.2 电机开关控制
电机控制的一个重 要元件就是开关。 许多类型的开关都 被用来控制电机。
他们常被用于与液体 或气动控制，继电器 或其它诸如钻床、车 床或传送带系统等电 动机驱动的机械相联。
在其最基本的形式中， 限位开关把机械运动 转换成电子控制电流。 注意凸轮通常安装在 电机上，是一个外部 零件。
The cam applies force to an actuator of the limit switch. The actuator is the part of the limit switch that cause the internal NO or NC contacts to change state. The actuator operates due to either linear or rotary motion of the cam, which applies force to the limit switch.
通常，按钮不是常 闭(NC)类型就是常 开(NO)类型。但是 有一些修改。
一个常闭按钮通常 是关闭的直到它被 用手按下，当它被 按下后将断开一个 电路。
The normally open pushbutton is open until it is manually depressed and, then, once it is depressed, it will close a circuit. The “start” pushbutton of a motor control station is of NO type, while the “stop” switches of NC type.
